This fuku deals which gives good rewards at 10k is relatively better than the past fuku deals which gives ninjas. Months before the change, fuku deals was giving out karin christmas fragments and danzo izanagi fragments, which weren't bad but just really two ninjas you would not use seriously. The ninjas being giving out shortly before the change were novelty ninjas or just ninjas you would not use in general. The power change on the other hand would benefit everyone and also alleviates the pressure from players feeling the need to complete the whole 20k or 30k range to get a ninja because the prizes given out this time are good even on the 10k and below range.

To sum it up, the pros for this week's fuku deals is as follows:

- Items that benefits everyone

- No pressure on having to complete the maxing 30k because it is optional

- Freedom to choose how much to spend with little to no consequence

Now for your claims about the 50% increase in the top reward, I think it's just that they made it into a declining scale of prizes the higher range you go into. Instead of thinking that this is a greedy move, let's give the benefit of the doubt and say that they put more emphasis on putting good rewards at the lower range of 10k and made 20k and 30k purely optional. And I say this with the outmost positivity since there have been worse times that the 20k prize is really not worth it but demands you do it to complete the ninja.
